Definitions

  • the invention relates to a space heater for small rooms, in particular for mobile spaces, such as caravans, vehicle and ship cabins, according to the preamble of claim 1.
  • a known boiler for heating air or water (DE-B-2 919 306) is equipped with a heat exchanger which surrounds an elongated combustion chamber cylinder at a distance and which is designed in the form of a wave jacket.
  • the deflected combustion gases and the outside the heating air are guided along these longitudinal wave channels distributed over the circumference of the jacket. Since the combustion chamber cylinder extends only to half the length of the heat exchanger and there is a larger circumferential gap between it and the shaft jacket, the combustion gases are deflected towards the outlet channel from the middle of the heat exchanger. Therefore, only a short heat exchanger section is heated effectively.
  • the inner shaft channels intended for removing the deflected combustion gases open into a collecting space which is formed around the burner between the strongly constricted combustion chamber cylinder and a front plate.
  • an exhaust gas channel is provided which increases the exhaust gas flow especially in these subsequent wave channels, while only a reduced exhaust of the combustion gases is achieved from the more distant wave channels and from the remote areas of the collecting space.
  • This uneven distribution of the combustion gases also leads to uneven heat transfer to the heat exchanger.
  • a housing jacket surrounding the heat exchanger is not suitable in its design and with its connecting channels for a flow of hot air, which is why this boiler cannot meet the requirements for a heater for small rooms.
  • Another heating device which is primarily designed to heat large amounts of air to supply greenhouses or the like to large rooms, provides for an extended combustion chamber cylinder which extends close to the end of the heat exchanger. Also, the waves of this wave jacket forming the heat exchanger lie on the inside on the combustion chamber cylinder and on the outside on an outer jacket, so that separate flow channels are present both for the deflected combustion gases and for the heating air to be heated. Since the heat exchanger extends to a front plate on the burner side, the inner shaft channels are open to a central collecting space created by a narrowed burner tube.
  • combustion gases to be removed are therefore collected centrally within the heat exchanger and discharged to the outside through an edge connection, which is why these combustion gases cannot be drawn off evenly from all the shaft channels.
  • This collecting space can also only be accommodated on relatively large-sized heaters.
  • the cross section of this heater and thus also that of the heat exchanger is square, so that the flow channels close to the corner are still further away from the exhaust duct and this makes uniform exhaust gas extraction even more difficult.
  • the complex design of this large-area heater cannot be used for a small-room heater either.
  • the invention is therefore based on the object to provide a heater for small rooms, which ensures a largely uniform combustion gas flow over the full extent and thereby a uniform and increased heating of the heating air and the construction of which is suitable for a particularly powerful small room heater.
  • the combustion gases and the heating air to be heated are fanned out on separate wave channels and guided along them, so that a uniform and intensive heat transfer can take place through this vortex-free flow around the heat exchanger , which heats the heating air flowing in the opposite direction quickly and effectively.
  • the flame tube which also surrounds the burner at a favorable distance, extends close to the end of the heat exchanger, which is why the combustion gases are also effective over the entire length of the heat exchanger, especially when the jacket shafts are heated directly by the flame tube.
  • a burner 2 in the space heater shown in simplified form, there is a burner 2, not described in more detail, in a combustion chamber 1.
  • a flame tube is fitted with this plug-on end 8 onto this burner 2.
  • This flame tube extends upwards in the interior of a heat exchanger 10, where it ends with its upper outlet opening 5 shortly before a ceiling surface 23 of the heat exchanger.
  • a protective plate 7 is placed on the flame tube, which protects the heat exchanger top surface 23 from overheating.
  • the flame tube is formed from a suitable and appropriately surface-treated sheet metal blank, expediently at least one expansion fold (not visible) is formed along a surface line to absorb thermal expansions that occur.
  • the heat exchanger 10 expediently a shaped piece made of an aluminum alloy, forms an annular space 11 at its open end by means of a base cylinder 13.
  • a base collar 14 can also be designed to hold the heat exchanger on a base attachment (not shown).
  • An outlet connection 12 leads from the annular space 11 for the extraction of the combustion gases to the outside.
  • the heat exchanger is formed by a wave jacket 15. This consists of waves 16 running evenly around the circumference, the outer wave crests 18 and inner wave troughs 17 of which lie on an imaginary circle.
  • the shaft walls 19, which delimit the inwardly open shaft channels 20, are approximately parallel to one another.
  • the combustion gases flow downwards after exiting the flame tube and are deflected at the ceiling surface 23, where they are taken up by the annular space 11 and finally discharged to the outside through the outlet connection 12.
  • the inner shaft channels 20 are closed at the top by deflecting walls 25, which slope downwards towards the outside and thereby form favorable deflecting surfaces for the combustion gases.
  • the annular space 11 formed by the base cylinder 13 is delimited on the outside by the transition walls 26.
  • the flame tube lies directly on the inner surfaces of the shafts 16, the heat is transferred directly from the flame tube to the heat exchanger.
  • the flame tube 3 adjacent to the wave troughs 17 closes off these wave channels, so that the combustion gases are divided into a large number of individual streams, which fall down in the form of relatively narrow flow layers and are surrounded by relatively large heating surfaces. This results in a very even distribution of the combustion gases and thus also a uniform heat emission over the entire circumference of the heat exchanger.
  • the annular space 11 acts here as a collecting space for the falling combustion gases and thus ensures their undisturbed extraction, even if there is only one outlet connection at one point.
  • the heat exchanger according to the invention can be set up without a casing or similar covering and can act directly on the room air, which flows up along its outer shaft channels 21 and heats up.
  • a more powerful device can be achieved in connection with a heating chamber jacket 28, which expediently surrounds the heat exchanger at full height and at a short distance from the wave crests 18.
  • An air inlet opening 29 at the level of the annular space 11 enables sufficient air access, a slight expansion 31 of the heating space jacket in the lower area ensuring a uniform distribution of the inflowing air around the heat exchanger.
  • the heating chamber jacket is brought together to form an air outlet opening 30, from which the heating air can either flow directly into the room to be heated or flow into a pipe system.
  • the invention is not limited to the illustrated embodiment.
  • a precisely cylindrical arrangement of the heat exchanger shaft jacket 15 and / or the flame tube 3 is also possible, although a predetermined conicity, which takes into account the gas concentration due to cooling and thereby avoids a flow delay, has a more advantageous effect.
  • the jacket shafts do not necessarily have to extend over the entire length of the heat exchanger, which can be the case, for example, if they can only start in an upper region because of a different design of the combustion chamber and / or the heating air duct. If in the heat exchanger shown, the jacket shafts are lined up in close succession, this includes a different design with z. B. wider wave valleys and / or mountains, which can also be different, not. It has proven to be particularly advantageous if the height of the jacket waves 16 is approximately one fifth to one half of the radius of the circle circumscribing the jacket waves.
